Abstract

An interferometer with a single-mode optical waveguide wound in a coil which waveguide has a surface at each end for the acceptance of the light into the waveguide ends and for the display of light in the waveguide characterized by an improvement comprising at least one optical directional coupler having four input/output ends being provided. One of the four input/output ends is coupled into one of the pair of ends of the waveguide forming the coil and a second of the input/output ends is coupled to the other end of the pair of ends of the waveguide forming the coil. Preferably, the coupling of light from a light source utilizes a second additional directional coupler, which has an input/output end coupled to a third input/output end of the first mentioned coupler and the device preferably has a pair of light sensitive elements with one of said elements receiving a superimposed image from the fourth input/output end of the first mentioned coupler and the other receiving light from one of the input/output ends of the second or additional coupler.
